Introduction:

This post will show you how to enable EIGRP routing for particular VRF’s. Enabling EIGRP inside a VRF requires few special commands as compared to enabling it for the GRT (Global Routing Table).

address-family ipv4 vrf {vrf_name}

• address-family ipv4 vrf – tells the router to enable EIGRP IPv4 routing for VRF
• {vrf_name} – This should be the VRF name for which you intend to enable routing

Configuration Example:
